Vanadium. Its Role for Humans
Plasma vanadium contents decline in three phases: The first phase is a rapid decline with a half-life t 1/2 of 1 hour, followed by a second intermediate decline (t 1/2 ≈ 26 hours) and a third slow decline with t 1/2 ≈ 10 days. Vanadium contents in blood are thus reduced to about 30% within the first 24 hours . Clearing occurs directly via ...
